Model 1200W:the power is related to the input voltage, the higher the input voltage, the greater the power. The maximum input current of the power supply is 20A. For example, when 12V is input, the maximum power is 240W; when 24V is input, the maximum power is 480W; when 30V is input, the maximum power is 600WModule parameters:Module model: sz-bt07cccv-a1Module name: 1200W boost constant current moduleModule nature: non isolated boost module (boost)Input voltage: dc10-60vInput current: 20A (max) (input current can reach 25A when input voltage of fan cooling is 12-24V)Static working current: 15mA (when 12V rises to 20V, the higher the output voltage, the higher the static overcurrent will increase)Output voltage: 12-83v continuously adjustable (the default output is adjusted to 19v for shipment, if you need to adjust to other voltage values, please explain. If there is a multimeter, the buyer can adjust it)12-83v fixed output (for batch customers)Output current: 18a Max over 10a, please strengthen heat dissipation (related to input and output differential pressure, the larger the differential pressure, the smaller the output current)Constant current range: 0.5-18a (+ / - 0.3A)Input anti reverse connection: Yes (150A power MOS anti reverse)Low battery protection: Yes (9-50v adjustable)Temperature controlled fan: Yes (turn on the fan when it is over 55 )Working temperature: - 40 ~ + 85 (please strengthen heat dissipation when the ambient temperature is too high)Working frequency: 150kHzConversion efficiency: 92% - 97% (efficiency is related to input, output voltage, current and differential pressure, low differential pressure and high efficiency)Input over-current protection: Yes (input over 25A, automatic protection, power supply does not boost)Short circuit protection: double short circuit protection (input 30A fuse), safer to use.Input reverse connection protection: there is (150A power MOS tube anti reverse). Can be reversed for a long time)Installation method: 4 3mm copper pillarsWiring mode: terminal block (please use high current pure copper wire)Module size: 130mm long, 52mm wide, 53mm highModule single weight: 300gOutput power: = input voltage * 20a, for example: input 12V * 20A = 240W the maximum power is 240W when input 12VInput voltage * 20A for example: input 24V * 20A = 480W, that is: when input 24V, the maximum power is 480WNote: the maximum power is 240W when 12V is input, 480W when 24V is input and 720W when 36V is inputOutput voltage / output current regulation / input low battery protection regulationVoltage regulation: use a slotted screwdriver to adjust the "v-adj" potentiometer (marked in the figure below) at the output end when the power supply is no-load. The output capacitance is large, and the response will be slow when the output voltage is adjusted from high voltage to low voltage. The adjustment range of Jianyi is smaller. (the default output voltage is adjusted to 19v for shipment. If we need to adjust other voltage values, please explain or leave a message)Current regulation: turn the "a-adj" potentiometer anticlockwise for about 30 turns, set the output current to the minimum, connect the LED or current, and turn the "a-adj" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, it will be connected to the output and transferred to the current you need. When charging, it is necessary to wait until the battery is discharged. Then the default output is transferred to 3A. If we need to adjust the current value, please do not use the short-circuit output mode to adjust the current. The circuit structure of the boost module cannot be adjusted by the short-circuit mode,Input low battery protection regulation: low battery protection is mainly used to prevent over discharge of battery when the input power supply is battery, and damage of power module and battery due to low battery voltage. For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module and use a slotted screwdriver to adjust rv1 (clockwise protection voltage value is adjusted higher, counterclockwise protection voltage is adjusted lower) until the UVLO light is on. At this time, the low battery protection voltage is 10V. When the battery voltage drops to 10V, the power module does not rise (input voltage is equal to output voltage)Model 1800W:1. With the airfoil, the heat dissipation is very good, the output power is greater (48V input plus fan power can be around 1800W when the fan is added).2. The temperature control fan, combined with the hydraulic bearing fan, is well balanced on the noise and heat dissipation. When the load is light, the fan does not rotate, and the load temperature reaches about 60 degrees, and the fan automatically turns. It can effectively reduce noise and prolong life.3. The main power pipe insulation board uses high grade alumina, and the thermal conductivity is 10 times as high as the ordina
